如何在通讯录中显示对话框

Question

我使用此代码作为按钮，之后我在“联系人活动”中：

btnPhonebook.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View v) {
            Intent pb = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI);
            startActivityForResult(pb, 1);
        }
    });

之后，会有一个包含许多联系人的联系人列表。现在我想要的是，每当我点击一个联系人时，都会显示一个对话框。我怎样才能做到这一点。任何人都可以帮助我，因为目前我没有问题如何制作它。我试过这个代码，但它没有用。

Dialog dialog = new Dialog(this);
            AlertDialog.Builder builder = new AlertDialog.Builder(this);
            builder.setTitle("Choose a phone number");

            ListView lp = new ListView(this);
            lp.setAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, android.R.id.text1, _listPhoneNumber));

            builder.setView(lp);
            dialog = builder.create();

我还将上面的代码放在onActivityResult（）方法中。

提前致谢。

Answer 1

而不是使用内置意图来显示联系人..为什么不自己构建列表，然后执行您打算做的事情。

或

您是否将对话框设置为.show（）？

Answer 2

非常简单，

progDailog = ProgressDialog.show(loginAct,"Process ", "please wait....",true,true);

new Thread ( new Runnable()
{
     public void run()
     {
      // your loading code goes here
     }
}).start();

 Handler progressHandler = new Handler() 
 {

     public void handleMessage(Message msg1) 
     {

         progDailog.dismiss();
         }
 }

Answer 3

您无法在原生联系人应用中显示Dialog。

但是，您可以自己提取联系人，并使用ListView在CheckBox中显示，然后继续下一步。

Here是最简单的ListView来显示联系人。你可以自己编辑。

Answer 4

我已在我的应用程序中完成了如何从listview获取联系人详细信息， 使用此数据，您可以显示对话框。

    lv.setClickable(true);
    lv.setOnItemClickListener(new AdapterView.OnItemClickListener() {

    @Override
    public void onItemClick(AdapterView <? > arg0, View arg1, int position, long arg3) {

        Object o = lv.getItemAtPosition(position);
        Toast.makeText(getApplicationContext(), o.toString(), Toast.LENGTH_LONG).show();
        String infoString = o.toString();
        String arr[] = infoString.split(",");
        String names[] = arr[1].split("=");
        id = Integer.parseInt(names[1]);
        System.out.println("info" + id);

        db = dh.getReadableDatabase();

        String select = "select * from '" + dh.tablename + "' WHERE adb_id='" + id + "' ";
        Cursor c = db.rawQuery(select, null);

        if (c.moveToFirst()) {

            name.setText(c.getString(1));
            address.setText(c.getString(2));
            contact.setText(c.getString(3));    
        }    
    }
});

Answer 5

如果您想在联系中使用对话框，那么您必须为联系人制作自己的自定义布局。例如，请参阅下面的代码... 点击按钮

public static final int NUMBER_SELECT = 1;
Intent intent = new Intent(clsBlockNumbers.this,CallLog_Activity.class);
startActivityForResult(intent,NUMBER_SELECT);

在同一个Activity中写/ make onActivityResult

protected void onActivityResult(int requestCode, int resultCode, Intent data)
        {
            switch(requestCode) {
            case NUMBER_SELECT: 
                if (resultCode == RESULT_OK) {
                    String number = data.getStringExtra("SelectedNumber");
                    if(number == null)
                    {
                        Toast.makeText(this, "No Record found: ", Toast.LENGTH_LONG).show();
                    }
                    else
                    {
                        //Your code
                    }
                    break;
                }

            }

        }
